Investigation of the Effects of Diesel-Biodiesel-Butanol-Butanol Mixture on Engine Performance

Abstract

The vast majority of the energy used in the world is obtained from fossil fuels. This situation increases external dependence in countries such as our country, which is constantly growing and developing. In addition, the fact that fossil fuels will end in the near future leads to price instability and environmental problems. These problems have pushed us to look for an alternative fuel, an alternative energy source. The low fuel consumption of the diesel engine and high compression ratios make the diesel engine very attractive for use in heavy duty vehicles. It is known that vegetable oils can be used as fuel in diesel engines without any processing, but when used for a long time, it causes clogging in the engine, fuel line, clogging of injectors, cold weather or difficulties in the first movement when the engine is cold. The conversion of oils into biodiesel by transesterification method is more suitable than the use of unprocessed oil. When we look at the fuel properties of biodiesel produced by transesterification method, although it is similar to diesel fuel, its viscosity value is higher than diesel. In this study, tests were carried out at various speeds to determine the characteristic properties of biodiesel, biodiesel -diesel fuel blend, biodiesel -butanol blend and biodiesel -diesel -butanol blends produced by transesterification method in a four cylinder four stroke direct injection diesel engine.
